GENERAL INFORMATION

The YorkGuard VI Demand Defrost control as a replacement part for prior versions of the YorkGuard control.

Following the detailed instructions for modifications of both the indoor and outdoor units is critical.

NOTE: For direct replacement of YorkGuard VI, replace the control only.

Service replacement kit consists of:

• YorkGuard “VI” Defrost Control.

CONTROL CONFIGURATION FOR

ALL APPLICATIONS

Most jumper settings should be set to match jumpers on board being removed.

Remove control from packaging and configure the control as follows:

1.Specify the desired Low Temperature Cut Out (LTCO) using the jumper on the control.

2.Specify the desired Balance Point (BP) using the jumper on the control.

3.Specify appropriate defrost curve using the jumper on the control. See Table 1.

4.Verify that the Y2 LOCK jumper is set. This jumper is not applicable to a single stage compressor system.

5.Specify if the Heat Pump is installed with a fossil fuel fur- nace using the FFUEL jumper. The jumper should be ON for a fossil fuel furnace installation and OFF for an air han- dler installation.

6.Specify Switch Point jumper using the jumper on the con- trol.

7.Verify that the HOT HEAT PUMP is set appropriately.

8.Specify compressor delay using jumper on the control. “ON” will shut-off compressor when entering and leaving defrost.
